-SPECLIFICATION forming part of Letters Patent N o. 648,688, dated May1, 1 900. Application mea september V15,1899. serian. 730,561.' (NoSpecimens.)

To alZZ whom it may concern:

- ducea gas from calcium carbid, such as used in the usualacetylene-machines for producing acetylene gas for` cooking and heating,

for the reason that such gas will not mix withA ordinary air in amixing-tube, such as commonly employed in connection with other gases,and therefore such acetylene gas could only be used for lightingpurposes..-

I have now discovered that by combining a mixture of liquidhydrocarbons, such. as gasolene, with the ,calcium carbid andsupplyingthe proper amount of water under the" same -principle and the samequantity as in -all acetylene-gas-producing machines a gas" can beproduced which when mixed with ordinary air and ignited will produce aflame equal to that produced by coal or any other gas for the purposestated at a minimum cost', the gas thus produced being 'also availablefor lighting purposes with the best results.

The drawing is a combined side` elevation and sectional view of avesselor can forming a part of the ordinary acetylene-gas machine, showing themixture contained therein.

In carrying out my process I employ or use about three and one-halfpounds calcium carbid to one quart of gasolene or a similar mixture ofliquid hydrocarbons,which ingredient, together. with .the liquidhydrocarbons, is

placed in a can, tank, or reservoirso constructed as to be readilyattached in its proper position to an acetylene-'gas-producing machine,Which machine automatically supplies a sucient quantity of water to themixed calcium carbid and liquid hydrocarbons contained in. said canautomatically at intervals and in the proper proportion, as in allmachines of this character.

Referring to the drawing, l represents the usual vessel or can forming apart of the or-- dinaryacetylene-gas machine; 2, a cap to which the sameis removably attached; 3, a

tained within the can,and 4 a gas-pipe through which the gas passes fromthe vessel to the lgasometer of -saidmachine, all of which is of thewell-known construction.

' It is obvious that by combining the amount of calcium carbid and thequantity of liquid hydrocarbons in the proportions above described theliquid hydrocarbons will not only be, thoroughly mixed with the calciumcarbid, but the level thereof will be a considerable distance abovethecalciu m carbid,where by when the Water is fed to the mixturethe samewill naturally pass through the liquid hydrocarbons and combine with thecalcium carbid and produce gas from the latter in the usual manner; butsaid gas when produced will pass throu gh theliquid hydrocarbons andthere mix with the same, producing gas of thenature. above described.Gas produced in the manner stated will not heat the tank or reservoir inwhich the same is generated,

las is a commonA annoyance and objectional pipe for supplying water tothe mixture con-' feature when gas is produced from the calcium carbidalone.

The gasolene or mixture of liquidphydrocarbone which I employ must befrom to 90, or what is known as high-test liquid hydrocarbons, toproduce the best resultsor a smokeless-flame when ignited and carriedout according to the above description. It is obvious, however, that theabove mixture of calcium carbid and liquid hydrocarbons may be made bythe consumer instead of supplying the mixture in cans or receptacles tobe attached to the machineby proper directions and description withoutdeparting from the nature of my discovery. A

In carrying out my 'process 'as above described no water whateverremains in the mixture, as the small quantity of said Water fed atintervals to the mixture combines immediately with the calcium carbidand produces gas, which passes through the liquid hyd rocarbons abovethe same and produces the gas, as before described.

Having fully described my process, what I claim as new, and desire tosecure by Letters Patent, is l The herein-described process formanufacturing gas, which consists in placing in a yes- IOO sel a.suitabe quantity of calcium carbid, and from the same, in the man-nerdescribed, and 1 liquid hydrocarbons, and' subsequently feedfor thepurpose set foi-Ish. 1o
